There are many types of polyurethane foaming machines on the market, and there are countless foaming machines of various brands, shapes and names, and new brands and names of foaming machines are constantly being introduced. The numerous models dazzled the producers, so that they chose the wrong model. In order to facilitate the producers to choose the foaming machine correctly, we will discuss the selection method of the foaming machine.
1. Fully understand the type of foaming machine
Although the basic principle of the foaming machine is to introduce gas into the foaming agent aqueous solution, different types of foaming machines introduce gas in different ways. Knowing the type of foaming machine will know its air-entraining method, which is very helpful to further understand its technical characteristics and performance, and helps the producer to grasp the overall.

For example, the low-speed stirring type uses slow-rotating blades to introduce gas, resulting in small bubble output and low foaming efficiency; high-speed impeller type uses high-speed rotating impellers to induce air, the bubble diameter cannot be controlled, and the foam is uneven; high-pressure and medium-low-pressure production The bubble speed is fast, the efficiency is high, and the bubbles are uniform and small.
After understanding the advantages and disadvantages of various types of foaming machines, it is easy to choose foaming machines. Therefore, a full understanding of the type of foaming machine plays a vital role in the correct choice of the foaming machine for the producer
